Finglow

Finglow is a suite of desktop calculation programs for designing and assessing pressure vessels and shell-and-tube heat exchangers. It covers the British PD5500 code, the European EN13445 standard, and ASME Section VIII Divisions 1 and 2. Engineers enter components such as shells, heads, nozzles and flanges. The software runs the code calculations, flags errors and code limits, and produces reports that engineers and inspectors use to review and approve designs. One distinctive feature lets a user build a design under one code and switch to another to see how compliance changes, with several codes cross-checked on the same screen. Each release comes with a verification manual. Finglow was originally a UK-developed product. Computer Engineering Inc. (CEI), which also makes DesignCalcs for ASME Div 1 and ProWrite for welding procedures, acquired it around 2019. Through CEI, Finglow integrates with NozzlePRO from Paulin Research Group, which adds finite element analysis of nozzles, saddles and clips. It suits fabricators and engineering firms that work to European and British codes as well as ASME. CEI does not publish prices. A customer picks a feature tier and the codes it needs, licenses the result as single-user or multi-user, and gets a quote. A free trial or demo is available on request. The main limitation is that independent evidence is very thin: there are almost no public user reviews, and the product is a niche Windows calculation tool rather than a modern cloud platform.
